Answer:

A is is correct since the interquatile or a is 15 since 15 plus 15 equals 30 and 20 plus 20 equals 40

B is incorrect since the interquare are not both 30

C is incorrect since both interquatiles are wrong

D is incorrect since the standrard devations are off

A graphic designer wants to translate rectangle DEFG using T–1, 2(x, y). The pre-image has coordinates D(–1, 3),

anygoal [31]

Answer:

D'(-2, 5), E'(3, 5), F'(3, 3), G'(-2, 3)

Step-by-step explanation:

Adding (-1, 2) to each of the coordinates gives ...

D +(-1, 2) = (-1-1, 3+2) = D'(-2, 5)

E +(-1, 2) = (4-1, 3+2) = E'(3, 5)

F +(-1, 2) = (4-1, 1+2) = F'(3, 3)

G +(-1, 2) = (-1-1, 1+2) = G'(-2, 3)

What is the equation for this graph or table? picture shown :D

ira [324]

The equation is
Y = 4x + 11

We know that the y intercept is 11 because it’s coordinate is when x is zero.

You can then use the formula (y2-y1)/(x2-x1).

Given the equation f(x) = (x + 3)2 – 8, fill in the blanks: Axis of symmetry: x = _______a0 Vertex: ( _______a1, _______a2) Numb

frutty [35]

We have been given an equation $f(x)=(x+3)^2-8$ . We are asked to fill in the blanks using our given equation.

The axis of symmetry will be the vertical line passing through vertex.

First of all, we will convert our given equation in standard vertex form of parabola as:

Standard vertex form of parabola: $y=(x-h)^2+k$ , where (h,k) is vertex of parabola.

$f(x)=(x-(-3))^2-8$

Upon comparing our function with standard vertex form, we can see that vertex of parabola is at $(-3,-8)$ .

The axis of symmetry will be vertical line passing through point $(-3,-8)$ . The vertical line will pass through $x=-3$ , therefore, the axis of symmetry is $x=-3$ .

Since our given parabola is an upward opening parabola, so it has a minimum at $(-3,-8)$ . This means that parabola will intersect the x-axis at two points. Therefore, there are two real solutions for the given function.
